How to reduce dangers while providing preventive maintenance data
BY FINLEY LEDBETTER, Group CBS, Inc.
While most discussions about avoiding electrical hazards focus on personal protective equipment (PPE), utility workers have a number of ways to protect themselves and their gear, including specialized equipment and remote actuation and racking systems that eliminate—rather than reduce—electrical hazard dangers, while providing preventive maintenance data that can help avoid future catastrophes.
Grounding systems are a crucially important component of any power supply system, because they directly impact public and employee safety, supply system reliability, power quality and life expectancy of power equipment. In spite of their crucial role in safe, reliable, and economic operation of...
Insulation Resistance (IR) test, often called Megger test, is more than 100 years old and assumed to be a very straightforward test. During my inspection and testing work in the past 15 years in Canada, US, and internationally, I have seen different practices of performing and interpretation of IR...

Remote field operations present the safety organization with a myriad of challenges when it comes to ensuring the safety of the people that you send out to work in the field every day. Without a doubt, this includes the line workers, but it also includes nearly every member of the staff whose...
Verifying the functionality and integrity of a grounding system is critical to maintaining a safe workspace. Unfortunately, the tests used to achieve this goal, as well as the standards used to assess them, have required a specialized skillset, often leaving these tests done improperly or not at...
For years, manufacturers of ground rods have strived to develop technical specifications for the electrical industry which address the specific needs and applications of clients and endusers alike. One reason for stressing the importance of this was to assure that the customer would receive what...
Taking care of your grounds and jumpers A lineman’s ground and jumper cables look and feel like they’re built to last forever, but looks can be deceiving. They get tossed in the truck, dropped in the mud, left hanging in the rain, and generally overlooked. With everyday use, we start...
When working in close proximity to exposed energized equipment or working on live electrical circuits, it’s necessary to protect not only the equipment being worked on but also the worker. Rubber insulating gloves and insulated hand tools are vital components of a successful PPE system and should...
If you wanted to create a recipe for disaster, the beginning of the 2021 wildfire season would be a good place to start. Nearly 90% of the western U.S. is suffering through extreme drought. The snowpack set new low levels there as well. A record-breaking heatwave steamrolled the Pacific Northwest...
The 25 kV Class 200 Ampere loadbreak separable insulated connector system didn't always have today's reputation for safety and reliability. As 25 kV Class loadbreak connectors increased in popularity in the 1980's and 1990's, utilities reported unacceptably high numbers of flashovers...
